Description

Title: Wall or floor system for a house or building.
DESCRIPTION
The invention relates to a wall or floor system according to the preamble of claim 1. The invention also relates to building elements arranged for forming, when built together, at least a blade (e.g. an inner wall, outer wall or other panel) of such a system.
A system according to the preamble of claim 1 is known from FR 2 577 959 A.
It is remarked that the term "wall or floor system" as referred to in the present text comprises various types of wall systems or floor systems, such as for example outside wall systems for a house or building, separation wall systems for use between adjacent buildings or between adjacent rooms of a building, floor systems for buildings, etcetera. A wall or floor system may for example also be a roof element or roof system for a house or building. Hereinafter, such a wall or floor system is often more specifically referred to as an "exterior wall system", wherein the first space is the "open air", the second space an "inside room" of the house or building, the first blade an "outside blade" (outer wall) of the system, at the side of the open air, and the second blade an "inside blade" (inner wall) of the system, at the side of the inside room. It has to be understood that such more specific references, mutatis mutandis, similarly apply with similar uses and advantages to other types of wall or floor systems, such as for example the abovementioned separation wall systems, floor systems, roof elements or roof systems.
As mentioned, such an exterior wall system may comprise an outside blade, at the side of the open air, and an inside blade, at the side of the inside room. An insulation layer between them may be formed of either a (stationary) air layer and/or a more or less solid insulation layer, e.g. of rock or glass wool or of synthetic foam.
An important function of the exterior wall system is to provide a separation between the inside and outside climate of the building or house. The exterior wall system provides that the cold is kept outside and the heat is kept inside during cold periods and vice versa in warm periods. The exterior wall system also fulfills the function of protection and comfort against rain, hard wind or storm. To mention some further things, the exterior wall system may play a role in: heat/cold insulation, light regulation, energy consumption/savings, ventilation, protection against wind/draught, protection against the sun, use of sunlight and solar heat, security, protection against burglary etc., admission to the building, part of the construction of the building, or aesthetic design of the building.
It is not always desirable that all functions of the exterior wall system are simultaneously or continuously present. This may be illustrated for the use of solar radiation (sunlight, solar heat). In general, solar radiation will often be blinded during the summer while it (especially its heat radiation and daylight) will often be welcomed during the winter. It thus could be desirable that this function of the exterior wall system would be switchable, enabling the user to control the sunlight and/or solar heat entering the house or building. One switchable solution for part of this aspect is already known, after all in the form of sun blinds etc., wherein a user (or sometimes, e.g. in utility buildings, a sensor controlled automatic system) is enabled to control when the sun radiation is admitted to the house or building and when not.
One aspect of the invention is to enable to control the heat insulating/conducting and/or the heat accumulating function of the exterior wall system structure. In the present structure of exterior wall systems it is not possible e.g. to switch the insulation off during the summer or to switch it on during the winter, and/or to make use in a switchable way of heat or cold accumulating properties of the exterior wall system or parts thereof.
Another aspect of the invention is to enhance the energy efficiency of the house or building, as well as providing energy savings.
For these purposes, the invention provides a wall or floor system for a house or building, bordering a first space from a second space, said system comprising: a first blade at the side of the first space; a second blade at the side of the second space; and switchable heat transfer means arranged to control heat and/or cold transfer between the first blade and/or the second blade, on the one hand, and the first space and/or the second space, on the other hand; wherein the switchable heat transfer means comprises at least one heat . exchange channel extending through or along the relevant blade or blades, the longitudinal direction of such heat exchange channel being substantially parallel to the relevant blade; and wherein the switchable heat transfer means further comprises at least one connection channel for switchably connecting at least one of said at least one heat exchange channel both with the first space and with the second space.
In a preferable embodiment, said switchably connecting is realized by means of controllable valves arranged for influencing air flow through the at least one heat exchange channel and the at least one connection channel.
In a further preferable embodiment, said switchably connecting is realized by means of at least one air propulsion device, such as at least one ventilator, arranged for influencing air flow through the at least one heat exchange channel and the at least one connection channel.
In a yet further preferable embodiment, the switchable heat transfer means is arranged to activate/inactivate accumulation of heat/cold originating from the first space and/or the second space into the first blade and/or second blade.
In a yet further preferable embodiment, the switchable heat transfer means is arranged to activate/inactivate the transfer or transport of heat/cold accumulated within the first blade and/or second blade to the first space and/or the second space.
In a yet further preferable embodiment, said at least one heat exchange channel comprises a number of substantially evenly distributed channels or ducts at the inside and/or outside of the relevant blade. In a yet further preferable embodiment, the relevant blade or blades is/are built by building elements like e.g. bricks etc., at least some of the building elements comprising inside holes and/or outside grooves which are arranged to form, when built together, closed or open channels which function as the at least one heat exchange channel and the at least one connection channel.
In a yet further preferable embodiment, the system is an exterior wall system for a house or building, the first space being the open air, the second space being an inside room of the house or building, the first blade being an outside blade of the system, at the side of the open air, and the second blade being an inside blade of the system, at the side op the inside room.
In a yet further preferable embodiment, the at least one heat exchange channel is in connection with at least one channel, duct, groove, etc., corresponding to at least one other object, such as a one-bladed or more bladed floor, wall or roof element, for heat exchange with said other object. For example, one or more heat exchange channels corresponding to an inside blade of an outside wall system according to the invention may be in connection with one or more heat exchange channels in a floor, which may for example be a one-bladed floor. In that way, the heat exchange potential can be further improved.
In a yet further preferable embodiment, the invention provides an assembly of at least two wall or floor systems, each according to any one of the preceding claims, wherein different heat exchange channels of different such wall or floor systems are in connection with one another.
The invention furthermore provides building elements arranged for forming, when built together, at least one of the first blade and/or the second blade of such a system according to any one of the abovementioned embodiments, at least some of the building elements comprising inside holes and/or outside grooves which are arranged to form, when built together, closed or open channels which function as the at least one heat exchange channel and the at least one connection channel.
Although not restricted to that, arranging the switchable heat transfer means such that it transfers heat or cold which is accumulated in the first blade and/or second blade to the first space and/or to the second space could be considered as a very interesting application of the present invention, which might lead to embodiments aiming at optimization of the first and/or second blade's heat/cold accumulation function.
Further details, aspects and embodiments of the invention will be described, by way of example only, with reference to the schematic figures in the enclosed drawing.
Fig. 1 shows, in three mutually perpendicular cross sections, an example of an embodiment of an exterior wall system according to the invention, wherein in one of these cross sections the lines A-A and B-B denote position of the other two cross sections, respectively.
Fig. 2 shows an example of another embodiment of an exterior wall system according to the invention, in three cross sections similar to those of Fig. 1.
Fig. 3 shows an example of yet another embodiment of an exterior wall system according to the invention, in two mutually perpendicular cross sections similar to two of the cross sections of Fig.1.
Fig. 4 shows an example of yet another embodiment of an exterior wall system according to the invention, in two cross sections similar to those of Fig. 3.
Fig. 5 shows an example of yet another embodiment of an exterior wall system according to the invention, in two cross sections similar to those of Fig. 3.
In the different embodiments of the different Figures 1-5, like reference signs are used to indicate like parts and like aspects.
Figure 1, including two perpendicular cross sections A-A and B-B respectively through the exterior wall system, shows a first exemplary embodiment of the exterior wall system according to the invention, which is located between the open air 1 and an inside room 2 of the house or building. The exterior wall system comprises an outside blade 3, at the side of the open air 1, and an inside blade 4, at the side of the inside room 2, having an insulation layer, consisting of a solid layer 5 and a stationary air layer 6 between them. The exterior wall system, moreover, comprises switchable heat transfer means arranged to transfer heat or cold accumulated in the inside blade 4 or -as illustrated in figure 4- in the outside blade or -as illustrated in figure 5- in both blades, to the open air or to the inside room.
The switchable heat transfer means comprises a heat exchange channel 7, in the shown example in fact a plurality of such heat exchange channels 7, which extends through or- as illustrated in figure 3- along the relevant blade or blades. The longitudinal direction of such heat exchange channels is substantially parallel to the relevant blade. In figure 1 the heat exchange channels extend in vertical direction through the inside blade. As the cross section B-B shows, the heat exchange channel structure comprises a number of substantially evenly distributed channels or ducts 7 at the inside and/or -as illustrated in figure 2 — the outside (viz. having the shape of grooves) of the relevant blade. The relevant blade or blades -viz. the inside blade in this exemplary embodiment- may be built by building elements like bricks etc., which building elements comprise inside holes and/or outside grooves which are arranged to form, when built together, closed or -as illustrated in figure 2- open vertical channels.
Figure 1 , moreover shows that the switchable heat transfer means comprises at least one switchable connection channel 8 both with the open air and with the inside room. In the embodiment shown in figure 1 two connection channels 8 -one at the topside and one at the underside- are provided, each having an outlet/inlet to/from the open air 1 as well as an outlet/inlet to/from the inside room 2. All outlets/inlets may be switchable by means of valves 9 - 12. Those switches may be actuated from any air conditioning system, e.g. in the following way:
Figure 2 shows an embodiment wherein the channels are made by means of (evenly spaced) grooves in the inside blades 4, thus forming (half) open channels 7 which, however, are covered by the solid insulation layer 5.
Figure 3 shows an embodiment in which the air layer 6 may be used either, when all valves 9 - 12 are closed, as a (stationary air) insulation layer between the inside and outside blades 3, 4, or as a part of the heat/cold exchange structure, viz. as (one wide) channel 7 for the exchange of heat or cold with the inside blade 4 and the transfer of the heat or cold to the open air 1 or the inside room 4, via the channels 8 and valves 9 - 12. Figure 4 shows mainly the same configuration as shown in figure 1 , in which however the heat/cold exchange and transfer channels are provided in the outside blade 3 instead of in the inside blade 4 as in the previous embodiments.
Figure 5 shows a configuration which comprises channel structures 7 in both the outside blade 3 and the inside blade. To be able to make use of the heat or cold which may be stored in the outside blade 3 and the inside blade 4 and to transfer it to the open air 1 or to the inside room or to transport warm or cold air from the open air 1 or from the inside room 4 in several situations, additional valves 13 are installed.
All valves 9 - 12 and 13 may be actuated under control of automatic means, e.g. an air condition control computer and sensor, or may be (e.g. additionally) manually controllable. Finally, it is noted that in some cases the use of one or more air propulsion devices, such as ventilators, may be useful in order to stimulate the air to flow through the channels. Additionally, it could be useful to support (or even to replace), the function of the relevant valve(s) 9 - 12 by switching on/off such air propulsion device(s), such as ventilator(s).
